Forty-two years ago, Martin Luther King Jr. delivered one of the most profound, awe-inspiring and important speeches in world history.
On August 28, 1963, the civil rights activist addressed more than 250,000 American citizens from the steps of the Lincoln Memorial in Washington, D.C. Five years before his death, King called for the end to racism in the five-plus-minute speech that served as a defining moment in the American Civil Rights Movement.
